Create and Populate a Map<Id, Sobject> Without Loops

July 25, 2012 by David Schach 7 Comments

There are many reasons to use Maps in Apex triggers. Sometimes I want to make a List of Contacts, but I want to pull each one by its ID. This is a good reason to abandon the List and to make a

Map&lt;id, Contact&gt;

1	Map<id, Contact>

. (Some will prefer to use

Map&lt;string, Contact&gt;

1	Map<string, Contact>

, and that is okay too.) We […]

Workflow ISCHANGED() translated to Apex trigger

February 2, 2012 by David Schach 2 Comments

Workflow is great. I can simply and declaratively make changes, and can easily update things like email templates, criteria, tasks, etc. without using Eclipse and writing/running unit tests. Sometimes, however, workflow isn’t enough; we need to use a trigger. Today, I had a use-case that when a DateTime field is filled, a contact (identified via […]

Best Practice: Multiple Chatter Posts of the Same File

August 11, 2011 by David Schach 1 Comment

Salesforce Administrators learn to remind users: “Search before you create a new lead.” Pretty simple, right? Duplicated records are a pain. Then why do I see some very accomplished Salesforce users in the Dreamforce app posting duplicate Content/Files in Chatter? Here are some examples from the Files tab: The better thing to do – assuming […]

Next Birthday Formula

July 6, 2011 by David Schach 4 Comments

How would you display your Contacts with upcoming birthdays? I’ve seen people use “Birthdays This Week,” “Birthdays This and Next Week,” and other reports to display the list. I’ve also seen requirements for showing a person’s next birthday, to trigger an automatic email to each Contact on his/her birthday. Let’s see how it’s done: [sourcecode […]

PageReference Best Practice

May 5, 2011 by David Schach 2 Comments

I've seen a lot of coders put the following into their custom Visualforce controllers:

public PageReference customsave() {
    try{ 
        insert acct; 
    } catch (DMLException e) { 
        /*do stuff here*/ 
    }
    PageReference acctPage = new PageReference ('/' + acct.id};
    acctPage.setRedirect(true);
    return acctPage;
}

public PageReference customsave() {

try{

insert acct;

} catch (DMLException e) {

/*do stuff here*/

}

PageReference acctPage = new PageReference ('/' + acct.id};

acctPage.setRedirect(true);

return acctPage;

}

I've decided that I don't like this approach. It feels too much like a URL hack, and though I'm sure that it will always work (meaning that salesforce.com will never change its way of referring to a record by

/&lt;recordID&gt;

1	/<recordID>

), […]
